I tunes won't start anymore. I can't even start it in safe mode. I re-installed but it didn't help. Any recommendations on what to try next?

Hey gt5037c,

Thanks for the question, great troubleshooting so far.

To isolate further, does the issue persist in a new user account? If so, follow these steps:

When troubleshooting system-wide issues with iTunes, there are a few different suggestion to try.

Check for viruses

Windows viruses can interfere with a variety of computer functions including iTunes. Make sure that you have current anti-virus software installed with updated virus definitions and use it to scan your system.

Check for anti-virus and/or Internet security software

Internet Security software itself can sometimes cause iTunes to quit unexpectedly. Try disabling the Internet Security software temporarily or exempting iTunes from any active scanning done by such software. If this resolves the issue, check with the maker of the software for an update to the software or its virus definitions. See the following article for more information: iTunes for Windows: Troubleshooting security software issues.

Conflicting processes

Sometimes other programs and startup items can conflict with iTunes, look at the following article to troubleshoot such conflicts:
